use the given conditions to write an equation for the line in point slope form passing through (-5,7) and (-8,6)

Answers

Answer 1

Answer: point slope form is
y-y1=m(x-x1)
where slope=m
and (x1,y1) is a given point

slope=(y2-y1)/(x2-x1)
slope=(6-7)/(-8-(-5))=-1/(-8+5)=-1/-3=1/3

pick any point
(x,y)
(-5,7)

y-7=1/3(x+5) or
y-6=1/3(x+8)

If the cost of an orange is 18 kobo, what is the cost of 185 orange?

Answers

Answer:

1 orange = 18

185 oranges = x

(cross multiply)

18*185 = x

x= 3,330 kobo

hope this helps

Answer:

3330 kobo

Step-by-step explanation:

We know that one orange costs 18 kobo and we want to find the cost of 185 oranges. We will need to use ratio's for this question. A ratio is to show how much of one thing there is compared to another. So,

1 orange : 18 kobo

185 oranges = ? kobo

185 ÷ 1 = 185

185 × 18 = 3330 kobo

The cost of 185 oranges is 3330 kobo considering that one orange is 18 kobo.

Simplify the polynomial.

1. 4a²b + 5 - 6a³b - 3a²b + 2a³b

Answers

$1.\n \n 4a^2b + 5 - 6a^3b - 3a^2b + 2a^3b = \n \n = - 6a^3b + 2a^3b +4a^2b - 3a^2b+ 5=\n \n= - 4a^3b + a^2b + 5$

4a²b + 5 - 6a³b - 3a²b + 2a³b

We first simplify similar expressions,

4a²b - 3a²b + 5 -6a³b + 2a³b

= a²b + 5 - 4a³b

Jesse drives to work. The distance Jesse’s car travels (d) on a number of gallons of gas (g) is given by the equation d = 15g. The constant of proportionality in terms of distance traveled per gallon of gas is?

Answers

I can only half answer this question, as it doesn't tell what form of distance is used

the equation is...

d=15g

Now lets solve for 1 gallon of gas

d=15g
d=15(1)
d=15

This means that for every 1 gallon of gas, 15 (insert missing unit of distance here) can be driven.

15/1=15

Answer:The constant of proportionality is 15.

Isabel wants a coat that costs $60. She has saved $42. What fraction of the amount she needs has she saved ?

Answers

Simple.....

you have this fraction...

$(42)/(60)$

simplify...

42/6=7
and
60/7=10

Thus... $(7)/(10)$

Thus, she has saved $(7)/(10)$ of the money.

He sum of two numbers is 46 and the difference is 2 . What are the numbers?large number is
the small number is

Answers

a + b = 46
a-b = 2

solve one of the equations for a...
a + b = 46
a = b + 2

solve for "b" using substitution...
(b + 2) + b = 46
2b + 2 = 46
2b = 44
b = 22

solve for "a" with substitution...
a + (22) = 46
a = 24

Smaller Number: 22
Bigger Number: 24

Let us condense your question in the form of system of equations,

x + y = 46
x - y = 2

Now, x = 46 - y

Thus,

46-y - y = 2

46 - 2y = 2

-2y = -44

Thus, y = 22.

x + y = 46

x + 22 = 46

Thus, x = 24.

Thus, the greater number is 24 and smaller number is 22.
